' invention relatesto-an apparatusof the class disclosed in my Patent #1,591,135

granted July '6, 1926. l a

",The object ofmy invention to provide Q 5 an apparatus capable of elevating water or otherliquidto a higher level by the utilization of the fall ofa body of water. or other liquid through a moderate distance and to accomplish thisobjec'tf in an automatic and. con- ;0 tinuous manner without a'ss'istance. from outside sourcesof power. a

, furtherobj ect of my invention is to provide an apparatus which will intermittently produce avacuum or condition of rarified-air c uum or;condition of-rarified air pressure to cause a liquid to be elevated successlvel'y into said closed receptacles; j

V 2 Itis. also an objectof my invention to provide a means whereby the liquid may be discharged'from said closed receptacles into .sep-

arate receptaclesby'the action of gravity and 1 elevated 'from sa-irl separate receptacles to F the succeeding higher closedreceptacle', in a .139 means of a singlejapparatus for this pur-c pose c Afurther object is to provide an appara v tusin which thevacuum producing apparatus may-be located atfany convenient place v vhere'amoderate fall "of water or Otl lQIillQ:

uid is available. V I r p a 5 A further object is to automatically control the operation-of the vacuum producing apparatus by mechanism responsive'to the level of theliquid therein which will be al- I ternately collected and discharged to a-lowe'r 2' levehjthus producing the desired vacuum by the lower levelp is to provide asingle unit having'a single ,(v'aeuum producmgelement winch 1s connect- "f ed toja series of superimposed closed recep ta'cles in 'such a manner as to produce a. vacpressure in a series of closed receptacles situ c ated one above the other and utilize said vac.-

the withdrawal of 'liquid and its descent to I Afifurther objectaofi the present invention ously, as *"distinguished from my Patent #1,591,135 wherein a plurality of vacuum producing elements are separately connected to separate closed receptacles.

Afurther object is to provide a simple controlling mechanism in thevacuum producing element which will be positive and automatic in its action and composed of few parts.

- A further obj ect is to provide a controlling mechanism in which the parts which control '60 the inlet and outlet valves are held from move-- ment until the actuating force increases to a desired amount, when said parts are released andthe Valves actuated with a sudden rapid movement. Further objects will appear hereinafter in the following detailed description. In the drawings, the figure isa side elevation,partly in section of my liquid elevating mechanism. 4 j

A supplyof water or otherliquid is de livered froma' moderate elevation to an open tank 1. The tank 1 is provided with an outletc2, whichis controlled by a valve 3, oper ati-ng in a cage 4. Beneath the open tank 1, is

Thevalve 8 is provided with a cage 9, having a seat 10 therein, on which the valve 8 operates. A drain'pipe ll'leadsc from the 'cagef9 5 to' any desirable lower point of discharge.

(On the bottom of'the tank 5, is located'a .85

bearing block 12, in which is pivoted'a lever 13;: On the end of the lever 13, is located a float 14; A block 15 is pivotallyattached to the other end of the lever 18-. ,Theblock 15 is attached to' a rod 16, which operates; in ,gi'iides 17 andl8. The upper end of the rod -16is located beneath the valve 3 and when in raised position, lifts, the valve 3;:

g The block '15 is -provided'witl1' a-pair'of V-shaped notches 19 and 20 in whichoperates'a latch 21. The latch 21 has a beveled endformed so as to'conform to the V-shaped notches in the block- 15.; The'ilatch'121 is mounted" in] a housing, 22, having a bushing :.2 z.in are; ndthe wtthmugh,which passes one end of the latch 21.

i V 25 is positioned between the collar 24 and the bushing 23. By adjusting the bushing 23 which is threaded into the housing 22, the.

pressure of the spring 25 may be regulated.

The falling of the'fl'oat14 To the valve 8 is attached a rod 26 which is providedat its upper end with a ball 27, seatedin a saddle 28 on the lever 13. l H a The operation of the vacuum producing mechanism thus described is as ."follows-z With the mechanism in the position shown in the drawing thetank 5has been substantially tl'noughtheoutlet 6, sufficientlyto cause the unsupportedfweight ofthe float 14 to overcometh'e pressure off-the latchinthe notch 19, whereupon the float 14 will WlllclDQGOll'lB engaged in-' the allows the valve 8lrtobecome seatedonits seat 10, thus'rlosingoff the'discharge pipe 7 and stopping the flow of liquid'th'erethrough.

simultaneously with the falling of the float '14 and the closing-of the valve 8', theblock androd 16 are raised. The rod 16 comes in contact with the valve 3 in its upward movement andraises the valve 3 thus permitting a fre'sh' 'supplyof liquid to pass from the upper tank 1 into the closed 'tank .5. The

liquid-"will rise in the tank'5 until the float issubinerged enough to ca'usesuflicient down ward pressure on, the block '15 to forceat'he latch 2l out'ot the notch '20; The float '14 will then suddenly rise'to the position shown in the drawingQwh'en theoutlet valve 8 will be opened andtheinlet'valve 3 closed: Thereupon 'tlie described. operation will re: pea t'ed; automatically.

'In' the operation of the apparatus 4 herein 7 shown, the tank 5 is notcompletely filled or emptied in one cycle of operation. Regula tion' of the action of the valves is: accounpli'shed by: varying the tension on the sp'rin g l 13 i 's ymhe tank ee is "A -greater tension will'causei a"'l-ong'er period t'o ela-psebetween the opening and elosing o't th valves and vice versa a lesser' pressure will shorten isaid' ericd.

supplied with liquid to bera'ised by means i of a pipe 37. A pipe 38 extends from the lowe art of he tank 36'to the up part I of the tank 33. Tanks 33, 34. and are provided with outwardly opening check valves 39, 40 and 41 which discharge into open .45 connects the open tat-1k with the upper part ofthe closed tank 34,1and a pipe 46 connects the open tank 43- with the upper part of the closed tank-3 5. Adischarge pipe tanks 42, 43-and 44 respectively pipe 47 leads fronrthe open tank 44 vto'the point I at which 'itis desired to deliver the elevated liquid. The lower ends of the pipes 45 and 46 are sealed in 'theawater in open tanks 42 and The operation of the unit herein described is as follows: The intermittentdischargeof the liquid from the tank 5: causes-an intermittent-vacuum to be formed in the closed tanks, 5, 33, 34 and 35. Theva'cuum in-the tank 33 will cause liquid tobe raisedl from'i'the tank- 36 into'the tank 33, through thepipe '38 lVhen the vacuum ceases andthe liquiid rises in tank 5,"the liquidfin thetank 33 will 'be "9 discharged throughthefoutlet check valve 39 into theop'enltank'42. The'nextformat ion 5 of the vacuum willfca use liquid to y be" raised from the tank 42 throughthe pipe '45 intot'h'e' closedtank 34; as well as ifr'oin the tankr'36 into the closed tank 33. When' the vacuum ceases, liquid will be' discharged" from; the I closed tanks 33 and 34 into-the open tanks 42 and 43 through the discharge check valves-39 and 40.
